UK: Scientist banned from revealing codes used to start luxury cars
The high court imposed an injunction on the University of Birmingham's Flavio Garcia, a lecturer in computer science, who has cracked the security system by discovering the unique algorithm that allows the car to verify the identity of the ignition key.
It complained that the publication could "allow someone, especially a sophisticated criminal gang with the right tools, to break the security and steal a car". The cars are protected by a system called Megamos Crypto, an algorithm which works out the codes that are sent between the key and the car.
The scientists wanted to publish their paper at the well-respected Usenix Security Symposium in Washington DC in August, but the court has imposed an interim injunction. Volkswagen had asked the scientists to publish a redacted version of their paper – Dismantling Megamos Crypto: Wirelessly Lockpicking a Vehicle Immobiliser – without the codes, but they declined.
It emerged in court that their complex mathematical investigation examined the software behind the code. It has been available on the internet since 2009.
